Bently Nevada 1900/65A 167699-02 Display Module General Purpose Equipment Monitor

Product Overview
The Bently Nevada 1900/65A 167699-02 is a rugged, rack-based general-purpose monitor engineered to deliver continuous vibration, position and temperature surveillance for mid-critical machines such as pumps, fans, compressors and motors. Combining proven 1900/65A signal-processing firmware with the high-reliability 167699-02 processor module, this solution translates raw sensor data into actionable health information—eliminating unexpected failures and extending asset life.
